comment. >>> a history-making move, senate republicans blocked chuck hagel from becoming the newest defense secretary for at least two more weeks. cnn's chief congressional correspondent dana bash has more for you. >> on this vote the yeas are 58, the nays are 40. >> reporter: it was a moment for the history books. >> the motion is not agreed to. >> reporter: chuck hagel fell short of the 60 votes needed to break a gop filibuster of his nomination to be defense secretary. only four republicans supported their former senate gop colleague. >> the filibuster of senator hagel's confirmation is unprecedented, i repeat, not a single nominee for secretary of defense ever in the history of our country has been filibustered, never, ever. >> reporter: republicans argued they need more time saying hagel is too controversial to be confirmed only days after getting through committee on a party line vote. >> the president has a right to appoint people in whom he has confidence, but we have a constitutional responsibility to consider the nominee. a number of the republican senators have questions.
